The eastbound span had to run on two-way operations Tuesday morning to accommodate commuters, meaning one lane was opened in each direction. 11 News cameras showed backups on Route 50 by 6 a.m., and they lasted most of the morning.

Officials said the westbound span was closed overnight for scheduled work. Just after midnight, workers said they saw unusual and slight vertical movement of the bridge, so they came off the span for safety reasons.

MdTA officials said a team of inspectors examined the bridge during the day Tuesday and found nothing out of the ordinary. The bridge has been found safe to travel.

Experts determined that the movement seen by workers was caused by wind patterns and tarps that were in place on the bridge towers for the ongoing rehabilitation work.
